The sync script takes the KVM kernel module sources from a recent kernel A and patch them so that kvm-kmod can build them for an ancient kernel B. Now you have two options where this kernel A could be located on sync: by default (LINUX unset), it is in kvm-kmod/linux-2.6 (that git submodule). Or you define a different local tree via LINUX=/path/to/kernel/A - like above.
